i am actually surprised that there are not more incidents..

My take is that most people really don't know how taxing a nearly 17H (this time of year) can be.

You see elderly and infirm people getting wheeled on the plane and sitting in Coach - it's amazing that there aren't more incidents!!

This has to be a real dilemma for CX and other polar carriers - at what point do they deny service outright and/or make the pax responsible for any diversion which must costs tens of thousands of dollars if not more..
